The present invention relates to a sliding door device consisting of a plurality of door bodies, each of which has an inclined surface that is not perpendicular to the door panel surface.

(Prior art) As shown in FIG.
~ Slide a plurality of door bodies formed on an inclined surface where the end faces a and b in the width direction of 5C are non-perpendicular to the door panel surface along the rail 2, etc., or use a door wheel or a hanging wheel. We are developing a sliding door device that rolls along a rail. Such a door body end face a,
In the structure of b, when the door bodies are housed in the door housing part (not shown), the end surfaces a and b rub against each other and easily overlap each other when the door bodies are housed in the door body housing part. This is to ensure that.

However, in this sliding door device, when the door body 5C is pressed toward the door body 5A as shown by arrow A when opening and closing the door body, the door bodies come into contact with each other at the inclined surfaces a and b, so that A separation force is generated between the door bodies, which causes the door bodies 5A to 5C to separate in the indoor/outdoor direction as shown by the two-dot chain line.If the door bodies are held in this state, the air/water tightness will deteriorate; Another problem was that it had a bad appearance.

(Problem that the device aims to solve) In consideration of the above-mentioned problems, the present device aims to provide a sliding door device in which, when multiple door bodies with inclined end faces are arranged in tandem, adjacent door bodies are arranged in an orderly manner without moving away from each other in the indoor/outdoor directions.

(Means for Solving the Problems) The present invention provides a sliding door device consisting of a plurality of door bodies in which the end faces in the width direction of the door bodies are formed into inclined surfaces that are not perpendicular to the door panel surface. A roller protruding toward the adjacent door body is provided on the end face of the door body, and a recessed portion is provided on the end face of the adjacent door body, into which the roller is removably fitted. When the door bodies are arranged in series, the rollers on the end face of one door body are engaged with the recesses on the end face of the adjacent door body, thereby preventing separation in the indoor-outdoor direction.

In this embodiment, as shown in FIGS. 1 and 6, the widthwise end surfaces of the door bodies 5A to 5C are at a non-perpendicular angle of, for example, 45 degrees with respect to the door body panel surface, as described above. At the same time, rollers 12 are provided at the upper and lower ends of the end surfaces so as to protrude toward the adjacent door bodies, and the rollers 12 are provided on the other side. An arc-shaped recess 13 into which it fits is provided. In this embodiment, as shown in FIG.
An example is shown in which blocks 14 and 15 provided with 3 are attached by screws 51. The engagement between the roller 12 and the recess 13 occurs when the door body 5A,
1B, even if a force is applied in the direction of the arrow Y, the engagement between the roller 12 and the recess 13 is not easily released, and if a relatively strong force in the direction of the arrow Y is applied, The engagement depth is such that the roller 12 rotates and the two are separated. Further, as shown in FIG. 6, a sealing material mounting groove 8c is formed in the vertical beam 8 forming the inclined surfaces a and b, and a sealing material 42 made of a rubber material or the like is arranged in a cascade in the mounting groove 8c. It is attached so that it can sometimes come into contact with the opposing inclined surface a or b.

In the present invention, each of the door bodies 5A to 5C may be moved independently, but by making them interlock, opening and closing operations become easier, so in this embodiment, a mechanism for interlocking the door bodies is used. has been established. This interlocking mechanism will be explained with reference to FIGS. 4 and 5.

The interlocking mechanism 24 of this embodiment has a movable connector 25
The movable connector 25 is composed of a fixed connector 26 and a connecting link 27, and the movable connector 25 has a plurality of rolling elements 25b attached to the upper and lower surfaces of a rectangular base plate 25a, and has elongated holes in the base plate 25a. 25c
This movable connector 25
is movably engaged along guides 21 provided over the entire length of the upper and lower crosspieces 7 and 7 of the door bodies 5A to 5C. Note that the rolling element 25
A slider may be attached in place of b.

The fixed connector 26 is a substantially L-shaped metal plate, and the movable connector 25, which moves within the guide 21 of the door body 5B, is attached via a link 27 to the fixed connector 26, which is attached to the door body 5A by a screw 28. A fixed connector 26 is attached to the door body 5B, and a movable connector 25 that moves within the guide 21 of the door body 5C is attached via a link 27. Moreover,

7, the door body 5C is also pulled out from the door housing part 4, and in the door frame 1, as shown in FIG. abutting, and as shown in FIG.
The roller 12 is fitted into the recess 13 and moves while being prevented from moving in the Y direction.

On the other hand, when all the door bodies 5A to 5C are stored in the door body storage section 4 from the building opening, i.e., the door frame 1, the door bodies 5A to 5C are stored in the door body storage section 4 in a stacked manner by performing the reverse operation to the above. In this case, while the door bodies 5A to 5C run through the door frame 1, the door bodies 5A to 5C are stored in a state where the rollers 12 and the recesses 13 are engaged with each other.
5C moves, and the hoist 6 moves from the upper rail 2a to 2a',
When the door body 5A-5B moves from 2b" to 2b', the roller 12 is separated from the recess 13 by being guided by these rails, and the door body 5
A to 5C are overlapped with each other.

The present invention has been explained above using examples, but when implementing the present invention, the effect can be expected even if the engagement mechanism between the roller 12 and the recess 13 is provided at either the upper or lower part of the door body, or at the middle part. . The present invention can also be applied to a case where a door roller is provided at the bottom of each of the door bodies 5A to 5C and the doors roll on the lower rail. In addition, when the interlocking mechanism 24 is provided, a structure in which the door is automatically opened and closed by a motor or the like, or a mechanism in which the door body is interlocked by pulling a string or chain, like the opening and closing mechanism of curtains, is also adopted. can.
Further, among the left and right end faces of the adjacent door bodies of the end door body, the end face that does not face the adjacent door body may not be an inclined surface but may be formed at right angles to the panel surface.

(Effects of the invention) As described above, in the present invention, a roller protruding in the direction of the adjacent door body is provided on at least one of the upper and lower parts of the end face of the door body, and the roller is provided on the end face of the adjacent door body. Since the roller is provided with a recess that is removably fitted into the roller, when the door bodies are arranged in series, the roller on one end face of the door body is engaged with the recess part on the end face of the adjacent door body. By doing so,
Since separation between the indoor and outdoor directions is prevented, the air and water tightness between the door bodies is improved, and the appearance is also improved. In addition, a recess is provided on the end face of one of the adjacent door bodies, and a roller is provided on the end face of the other door body, and the two are butt-fitted to maintain air and water tightness, so there is no slight misalignment between the adjacent door bodies. Even if the door bodies are brought together or separated, the roller can be smoothly fitted into and removed from the recess, making it easy to use.Moreover, the effect of preventing the separation of adjacent door bodies in the indoor and outdoor directions is due to the roller's effect. The same effect can be obtained when a protrusion is used instead.
